Description
本申請要求於2017年10月24日提交的第62/576,257號的美國臨時申請的權益。上述申請的全部公開內容藉由引用併入本文。 This application claims the benefit of US Provisional Application No. 62/576,257, filed October 24, 2017. The entire disclosures of the above applications are incorporated herein by reference.
本發明關於控制閥組件。更具體地,本發明關於自鎖式電磁致動閥組件,其可用於各種應用,包括但不限於氣動。 The present invention relates to control valve assemblies. More specifically, the present invention relates to self-locking solenoid actuated valve assemblies that can be used in a variety of applications, including but not limited to pneumatics.
本部分提供與本發明有關的背景資訊,背景資訊不一定是先前技術。 This section provides background information related to the present disclosure which is not necessarily prior art.
螺線管是眾所周知的機電裝置,用來將電能轉換成機械能,特別是轉換成短衝程機械運動。因此,長期以來,人們一直採用螺線管回應電訊號來驅動閥。例如,在先前技術中已知使用螺線管使閥構件在致動方向上抵抗回復彈簧的偏置力移動。當向螺線管中的線圈提供電力時,在螺線管中產生磁場,使閥構件從休止位置移動到致動位置。當電磁鐵的電力中斷時,回復彈簧使閥構件偏置回休止位置。然而,這種方法的缺點是,螺線管的線圈必須始終保持供電,以抵抗回復彈簧的偏置力而將閥構件保 持在致動位置。非期望的、不經意間或甚至按照計畫的中斷對線圈的電力均會導致閥構件返回到休止位置,而不管這是否是需要的。在需要考慮螺線管的功耗的應用中,例如存在有限的電力來源(例如,電池供電的閥)的情況下,必須連續供電以將閥構件保持在致動位置的螺線管是不理想的。此外,在必須持續供電以將閥構件保持在致動位置的螺線管中可能出現顯著的熱量積聚。 Solenoids are well known electromechanical devices used to convert electrical energy into mechanical energy, particularly into short-stroke mechanical motion. Therefore, for a long time, solenoids have been used to drive valves in response to electrical signals. For example, it is known in the prior art to use a solenoid to move a valve member in the actuation direction against the biasing force of a return spring. When power is supplied to the coil in the solenoid, a magnetic field is generated in the solenoid, moving the valve member from the rest position to the actuated position. When power to the electromagnet is interrupted, the return spring biases the valve member back to the rest position. The disadvantage of this approach, however, is that the solenoid coil must remain powered at all times to hold the valve member against the biasing force of the return spring. Hold in the actuated position. Undesirable, inadvertent, or even planned interruption of power to the coil can cause the valve member to return to the rest position, whether or not this is desired. In applications where the power consumption of the solenoid needs to be considered, such as where there is a limited source of power (eg, a battery powered valve), a solenoid that must be continuously powered to hold the valve member in the actuated position is not ideal of. In addition, significant heat build-up can occur in the solenoid that must be continuously powered to hold the valve member in the actuated position.
為了降低螺線管的功耗和熱量集聚,特別是在螺線管要被保持在致動位置很長一段時間的應用中,永磁體(PM)已被用於在不需要對螺線管的線圈連續供電的情況下將螺線管的機械輸出保持在一個位置或另一個位置。先前技術中已知的常規自鎖螺線管通常採用滑動推銷和固定永磁體,其可以藉由電流脈衝鎖閉或解除鎖閉。沿一個方向流經螺線管線圈的電流增加(即,增強)永磁體的吸引力,並使得永磁體排斥推銷並與回復彈簧的偏置力相反地將推銷推向閥構件。當電流沿使永磁體的吸引力減少(即,削弱)的相反方向流過螺線管的線圈時,回復彈簧沿相反方向偏置閥構件。這樣,在相對短的電流脈衝流過螺線管的線圈之後,藉由致動螺線管,閥構件可以移動到並保持在任何預定位置。在永磁體的吸引力增加(即,增強)或減小(即,削弱)之後,可以切斷電力,並且閥構件將保持在其當前位置,而無論當前位置是致動位置還是休止位置。儘管先前技術中已知自鎖式電磁致動閥,但仍然需要改進自鎖式電磁致動閥。對於小型氣動閥來說尤其如此。 In order to reduce power consumption and heat build-up of the solenoid, especially in applications where the solenoid is to be held in the actuated position for a long time, permanent magnets (PM) have been used when there is no need for the solenoid The solenoid's mechanical output is held in one position or another while the coil is continuously powered. Conventional self-locking solenoids known in the prior art typically employ sliding pins and stationary permanent magnets, which can be latched or unlatched by current pulses. Current flowing through the solenoid coil in one direction increases (ie, enhances) the attractive force of the permanent magnet and causes the permanent magnet to repel the pusher and push the pusher toward the valve member against the biasing force of the return spring. The return spring biases the valve member in the opposite direction when current flows through the coil of the solenoid in the opposite direction that reduces (ie, weakens) the attractive force of the permanent magnet. In this way, the valve member can be moved to and held in any predetermined position by actuating the solenoid after a relatively short current pulse has flowed through the coil of the solenoid. After the attraction force of the permanent magnet increases (ie increases) or decreases (ie weakens), power can be cut off and the valve member will remain in its current position, whether the current position is the actuated or resting position. Although self-locking solenoid-actuated valves are known in the prior art, there is still a need for improvements in self-locking solenoid-actuated valves. This is especially true for small pneumatic valves.
本部分提供本發明的總體概述,而並非是本發明的全部範圍或所有特徵的全面揭露。 This section provides a general overview of the invention, and is not a comprehensive disclosure of its full scope or all features.
本發明主題描述了一種改進的閉鎖控制閥組件。閉鎖控制閥組件具有包括殼體、線筒和線圈的螺線管。線筒設置在殼體內,並且線圈繞線筒延伸。殼體在第一殼體端和第二殼體端之間縱向地延伸,並且線筒限定了沿縱向軸線延伸的螺線管孔。閉鎖控制閥組件還包括閥體、閥座構件和閥構件。閥體自螺線管的第一殼體端縱向地延伸。閥體限定閥體孔,閥座構件設置在閥體孔內。閥構件具有滑動地設置在螺線管孔內的頭部和滑動地設置在閥體孔內的閥部。閥構件的閥部具有閥座接合構件,該閥座接合構件向外延伸以在閥構件於螺線管孔和閥體孔中滑動運動期間接合閥座構件。閥構件在螺線管孔和閥體孔內、於第一位置和第二位置之間滑動,在第一位置,閥座接合構件遠離螺線管的第一殼體端移位,在第二位置,閥座接合構件朝向螺線管的第一殼體端移位。閥體包括端口面。閥座接合構件操作為在閥構件於第一位置和第二位置之間縱向地滑動時打開和關閉閥體的端口面中的一個或多個端口。偏置部件操作為向閥構件施加偏置力。偏置力使閥構件朝向第一位置偏置。永磁體至少部分地設置在螺線管孔內。永磁體具有磁場,並且操作為向閥構件施加吸引力。由永磁體產生的吸引力指向螺線管的第二殼體端,使得永磁體的吸引力與偏置部件的偏置力相對抗。在螺線管孔內 還設置有極靴。極靴定位在螺線管孔中並且在縱向上定位在永磁體和閥構件的頭部之間。永磁體的吸引力具有可變量值。當螺線管的線圈接收到特定極性的電流脈衝時,由永磁體產生的吸引力的可變量值發生變化。當永磁體的吸引力的可變量值大於偏置部件的偏置力時,該吸引力操作以使閥構件朝向第二位置移位。另一方面,當吸引力的可變量值小於偏置部件的偏置力時,偏置部件的偏置力操作以使閥構件朝向第一位置移位。這是藉由使施加到螺線管的線圈上的電流脈衝的極性反向來實現的。 The inventive subject matter describes an improved latching control valve assembly. The latch control valve assembly has a solenoid including a housing, a spool, and a coil. A bobbin is provided within the housing, and the coil bobbin extends. The housing extends longitudinally between the first housing end and the second housing end, and the spool defines a solenoid bore extending along the longitudinal axis. The latch control valve assembly also includes a valve body, a valve seat member, and a valve member. A valve body extends longitudinally from the first housing end of the solenoid. The valve body defines a valve body bore, and the valve seat member is disposed within the valve body bore. The valve member has a head portion slidably disposed within the solenoid bore and a valve portion slidably disposed within the valve body bore. The valve portion of the valve member has a valve seat engagement member extending outwardly to engage the valve seat member during sliding movement of the valve member within the solenoid bore and the valve body bore. The valve member slides within the solenoid bore and the valve body bore between a first position in which the valve seat engaging member is displaced away from the first housing end of the solenoid, and a second position in which the valve seat engagement member is displaced away from the first housing end of the solenoid, and a second position position, the valve seat engagement member is displaced toward the first housing end of the solenoid. The valve body includes port faces. The valve seat engagement member operates to open and close one or more ports in the port face of the valve body when the valve member is longitudinally slid between the first position and the second position. The biasing member operates to apply a biasing force to the valve member. The biasing force biases the valve member toward the first position. A permanent magnet is disposed at least partially within the solenoid bore. The permanent magnet has a magnetic field and operates to apply an attractive force to the valve member. The attractive force created by the permanent magnet is directed towards the second housing end of the solenoid such that the attractive force of the permanent magnet opposes the biasing force of the biasing member. inside the solenoid hole Pole shoes are also provided. A pole piece is positioned in the solenoid bore and longitudinally positioned between the permanent magnet and the head of the valve member. The attractive force of a permanent magnet has a variable value. When the coil of the solenoid receives a current pulse of a specific polarity, the variable value of the attractive force created by the permanent magnet changes. When the variable value of the attractive force of the permanent magnet is greater than the biasing force of the biasing member, the attractive force operates to displace the valve member towards the second position. On the other hand, when the variable amount of the attractive force is smaller than the biasing force of the biasing member, the biasing force of the biasing member operates to displace the valve member toward the first position. This is accomplished by reversing the polarity of the current pulses applied to the coils of the solenoid.
本發明的閉鎖控制閥組件中的永磁體的吸引力作用於閥構件本身,從而將閥構件拉向極靴。有利地,這消除了對常規的自鎖式電磁致動閥的滑動推銷的需要。本發明主題還消除了將偏置部件定位在閥體的遠端的需要,從而減少了閥體的長度。這意味著本發明的閉鎖控制閥組件需要安裝有該閉鎖控制閥組件的閥歧管中具有較淺的腔,從而提供更緊湊和更高效的空間利用。同時,本發明的閉鎖控制閥組件保留了與自閉鎖電磁致動閥相關的優點,包括與傳統電磁致動閥相比顯著降低功耗和熱量積聚。這使得本發明的閉鎖控制閥組件適於作為電池供電的應用和/或螺線管必須長時間地將閥構件保持在致動位置的應用的候選。 The attractive force of the permanent magnets in the latching control valve assembly of the present invention acts on the valve member itself, pulling the valve member towards the pole piece. Advantageously, this eliminates the need for a sliding push of conventional self-locking solenoid actuated valves. The inventive subject matter also eliminates the need to locate the biasing member at the distal end of the valve body, thereby reducing the length of the valve body. This means that the latching control valve assembly of the present invention requires a shallower cavity in the valve manifold in which the latching control valve assembly is mounted, thereby providing a more compact and efficient space utilization. At the same time, the latching control valve assembly of the present invention retains the advantages associated with self-latching solenoid-actuated valves, including significantly reduced power consumption and heat build-up compared to conventional solenoid-actuated valves. This makes the latching control valve assembly of the present invention suitable as a candidate for battery powered applications and/or applications where the solenoid must hold the valve member in the actuated position for extended periods of time.

殼體24之間。螺線管22的殼體24在縱向上於第一殼體端30和第二殼體端32之間延伸。線筒26包括外表面34和內表面36。線筒26的內表面36限定了沿縱向軸線40延伸的螺線管孔38。線圈28包括由繞線筒26的外表面34延伸的導線形成的繞組42。在所示的實施例中,當從沿縱向軸線40與第二殼體端32相鄰近地布置的點44處觀察時(即,當如圖2所示那樣從上方觀察螺線管22時),線圈28的繞組42繞線筒26沿順時針方向纏繞。應當理解,線圈28可以繞線筒26沿逆時針方向纏繞,然而,將必須對閉鎖控制閥組件20進行其他對應的改變,這將在下面描述。繞組42的導線可以由各種不同的材料製成。舉例來說但並非進行限制,繞組42的導線可以由漆包銅(Cu)製成。還應當理解,在不脫離本發明的範圍的情況下,殼體24和線筒26可以具有各種不同的形狀。作為非限制性示例,殼體24和線筒26的形狀通常可以為圓柱形,如圖式所示。
Referring to FIGS. 1-5 , the latching
圖1至圖5所示的閉鎖控制閥組件20包括端蓋46,該端蓋46被保持在螺線管22的第二殼體端32上。端蓋46可以以各種不同的方式固定到螺線管22的殼體24上。在圖示的示例中,端蓋46藉由卡扣元件48緊固到螺線管22的第二殼體端32。卡扣元件48具有斜坡形狀並卡扣在端蓋46的開口50中,以將端蓋46保持在適當的位置。閉鎖控制閥組件20還包括電氣地連接到螺線管22的線圈28的至少兩個電連接器52。例如,上述至少兩個電連接器52可以包括第一端子54和第二端子56。第一端子54和第二端子56可以具
有各種不同的形狀和構型。在所示示例中,第一端子54和第二端子56是從第二殼體端32縱向向外延伸並穿過端蓋46的導電銷。
The latch
閉鎖控制閥組件20還包括閥體58。閥體58自第一殼體端30縱向地延伸,並具有近端60、遠端62以及在閥體58的近端60和遠端62之間可測量的長度L。閥體58的近端60設置成相鄰於第一殼體端30,閥體58的遠端62與第一殼體端30縱向地間隔開。閥體58的近端60附接到螺線管22的第一殼體端30。舉例來說但並非進行限制,閥體58的近端60可以與螺線管22的第一殼體端30螺紋地接合。
The latch
如圖4和圖5最佳示出,閥體58限定了閥體孔64,該閥體孔64與螺線管孔38的縱向軸線40同軸地定向。閥體孔64具有沿橫向於縱向軸線40的方向橫跨閥體孔64延伸的孔徑66。在閥體孔64內設置有一個或多個閥座構件68a、68b。雖然其他構型是可能的,但在圖示的示例中,閥座構件68a、68b延伸到閥體孔64內並與閥體孔64螺紋地接合。閥座構件68a、68b可以是圓柱形的,並且具有沿橫向於縱向軸線40的方向橫跨閥座構件68a、68b延伸的內徑70。閥座構件68a、68b還可以包括密封件72,密封件72在閥體孔64內密封閥座構件68a、68b,以防止流體洩漏到閥座構件68a、68b與閥體58之間的閥體孔64內。
As best shown in FIGS. 4 and 5 , the
閉鎖控制閥組件20包括與縱向軸線40同軸地定向的閥構件74。閥構件74具有外表面76、頭部78和閥部80。如圖4和圖5所示,閥構件74是單件式部件,其中閥構
件74的頭部78和閥部80彼此成一體。頭部78滑動地設置在螺線管孔38內,閥部80滑動地設置在閥體孔64內,使得閥構件74可以在第一位置(圖4)和第二位置(圖5)之間縱向地平移。在頭部78處,閥構件74的外表面76面向線筒26的內表面36並以與線筒26的內表面36滑動配合的方式布置。可選地,閥構件74的外表面76可以在頭部78處具有圓柱形形狀。
The latch
閥構件74的閥部80包括閥座接合構件82,該閥座接合構件82徑向向外地延伸以在閥構件74於閥體孔64中的滑動運動期間接合閥座構件68a、68b。閥座接合構件82可以具有圓形橫截面形狀,並且可以限定在橫向於縱向軸線40的方向上橫跨閥座接合構件82的外徑84。如圖4所示,當閥構件74滑動到第一位置時,閥座接合構件82遠離螺線管22的第一殼體端30移位。如圖5所示,當閥構件74滑動到第二位置時,閥座接合構件82朝向螺線管22的第一殼體端30移位。閥座接合構件82可以由各種不同的材料製成。例如,但並非進行限制,閥座接合構件82的至少一部分可以由諸如橡膠之類的彈性材料製成。閥構件74的閥部80也可以具有各種不同的形狀。例如,閥構件74的閥部80可以具有提升閥形狀(圖示的)或滑閥形狀(未圖示)。當閥構件74的閥部80構造為提升閥時,閥座接合構件82的外徑84大於閥座構件68a、68b的內徑70。當閥構件74的閥部80構造為滑閥時,閥座接合構件82的外徑84近似等於閥座構件68a、68b的內徑70。
The
閥構件74的閥部80還可以包括鄰近閥體58的遠端62的第一活塞86和鄰近閥體58的近端60的第二活塞88。第一活塞86和第二活塞88操作用以密封閥座構件68a、68b。可選地,第一活塞86和第二活塞88可以具有基本相等的直徑,使得反向地作用於第一活塞86和第二活塞88的加壓流體導致在閥構件74上作用有平衡的壓力。這種構型有時被描述為壓力平衡閥。第一活塞86和第二活塞88中每一者均可以包括環狀溝槽90和設置在環狀溝槽90中的彈性活塞密封件92,該彈性活塞密封件92以緊密公差配合可滑動地且密封地接合閥座構件68a、68b,以防止流體洩漏到第一活塞86和第二活塞88與閥座構件68a、68b之間的閥體孔64內。
The
閥體58包括端口面94、第一端口96、第二端口98和第三端口100。第一端口96從閥體孔64到端口面94地延伸穿過閥體58,並且鄰近遠端62地定位在閥體58內。第二端口98從閥體孔64到端口面94地延伸穿過閥體58,並且在縱向上定位在第一端口96和第三端口100之間。第三端口100從閥體孔64到端口面94地延伸穿過閥體58,並且鄰近近端60地定位在閥體58內。第一端口96和第三端口100在縱向上定位在閥構件74的閥座接合構件82的相反兩側上。當閥構件74處於第一位置時(圖4),閥座接合構件82接觸閥座構件68a並密封閥座構件68a,以關閉第一端口96並打開第三端口100。因此,當閥構件74處於第一位置時,形成第一流體流動路徑102,其中流體可以從第二端口98到第三端口
100地或從第三端口100到第二端口98地流經閥體孔64。當閥構件74處於第二位置時(圖5),閥座接合構件82接觸閥座構件68b並密封閥座構件68b,以打開第一端口96並關閉第三端口100。因此,當閥構件74處於第二位置時,形成第二流體流動路徑104,其中流體可以從第一端口96到第二端口98地或從第二端口98到第一端口96地流經閥體孔64。
The
參照圖3,閥體58的端口面94構造為容納於閥歧管108的腔106中。在所示示例中,閥體58螺紋地接合於閥歧管108的腔106內,然而,閥體58可以藉由替代結構緊固到閥歧管108。閥體58還可以包括o形環110,o形環110在閥歧管108的腔106內密封閥體58,以防止流體洩漏到閥體58和閥歧管108之間的腔106內。閥歧管108可以包括一個或多個流體通道(未示出),該流體通道將流體傳送到閥體58中的第一端口96、第二端口98和第三端口100或從閥體58中的第一端口96、第二端口98和第三端口100中將流體傳送出來。例如但並非進行限制,閥歧管108可以構造成使得閥體58中的第一端口96操作為接收流體的入口端口,第二端口98操作為排放流體的出口端口,並且第三端口100操作為同樣排放液體的出口端口。
Referring to FIG. 3 , the
參照圖4和圖5,閉鎖控制閥組件20還可以包括設置在螺線管22的殼體24內的襯套112。襯套112可以包括凸緣部分114和頸部116,凸緣部分114定位於第一殼體端30內,頸部116延伸到螺線管孔38內、使得頸部116在徑向上定位在閥構件74的頭部78和線筒26之間。雖然其他構型
是可能的,但在所示示例中,襯套112的凸緣部分114與第一殼體端30螺紋地接合,並且襯套112的頸部116呈圓筒形。閉鎖控制閥組件20還包括偏置部件118,偏置部件118在縱向上定位在閥構件74的第二活塞88和襯套112的凸緣部分114之間。偏置部件118操作用以向閥構件74施加偏置力120。由偏置部件118產生的偏置力120指向閥體58的遠端62,因此使閥構件74朝向第一位置偏置。雖然偏置部件118可以採取若干形式,但在所示示例中,偏置部件118是繞閥構件74的頭部78螺旋地/環狀地延伸的壓縮彈簧。
Referring to FIGS. 4 and 5 , the latch
閉鎖控制閥組件20還包括永磁體122,永磁體122設置在螺線管22的第二殼體端32內。永磁體122具有面向閥構件74的頭部78的內端124和面向端蓋46的外端126。在圖示的示例中,永磁體122完全設置在螺線管孔38內;然而,在其他實施例中,永磁體122可以僅部分地延伸到螺線管孔38內,使得永磁體122的一部分位於螺線管孔38的外側。在運行中,永磁體122、有時縮寫為PM,可以選擇性地產生磁場並向閥構件74施加吸引力128。由永磁體122產生的吸引力128指向螺線管22的第二殼體端32,使得永磁體122的吸引力128與偏置部件118的偏置力120相對抗。
The latch
閉鎖控制閥組件20還包括極靴130,該極靴130設置在螺線管孔38內,並且在縱向上定位在永磁體122的內端124與閥構件74的頭部78之間。極靴130在面對閥構件74的頭部78的第一端132和抵接永磁體122的內端124的第二端134之間縱向地延伸。永磁體122的磁場保持永磁體
122抵靠極靴130。因此,在閉鎖控制閥組件20的操作期間,極靴130的第二端134與永磁體122的內端124之間的接觸保持恆定。換言之,在閉鎖控制閥組件20的操作期間,永磁體122不會相對於極靴130縱向地移動。然而,在以下文說明的方式調整極靴130的縱向位置時,永磁體122與極靴130一起相對於線筒26縱向地移動。
The latch
當閥構件74處於第一位置時(圖4),閥構件74的頭部78和極靴130的第一端132彼此縱向地間隔開一間隙136。當閥構件74處於第二位置時(圖5),閥構件74的頭部78移動至最接近極靴130的第一端132的位置,使得間隙136最小或減小。間隙136的大小對螺線管22的性能至關重要。由本發明主題設計提供的極靴130的調整有利地使得能夠針對最佳性能來設置間隙136。極靴130布置成與線筒26螺紋接合,以提供極靴130相對於閥構件74的頭部78的可調的縱向定位。線筒26的內表面36具有陰螺紋138,而極靴130在鄰近極靴130的第一端132的位置處具有陽螺紋140。極靴130的陽螺紋140與線筒26的陰螺紋138螺紋地接合,使得極靴130在線筒26的螺線管孔38內的相對旋轉使極靴130縱向地移位。當閥構件74處於第一位置時,極靴130在線筒26的螺線管孔38內的旋轉改變存在於閥構件74的頭部78與極靴130的第一端132之間的間隙136。為了便於調整極靴130在螺線管孔38內的縱向位置,極靴130的第二端134可以可選地包括工具接合接口142。極靴130由永磁體122的磁場延伸以包圍閥構件74的頭部78的至少一部分的材料製成。舉
例來說但並非進行限制,極靴130可以由鍍鎳的AISI 12L14碳鋼或AISI 430F不鏽鋼製成。
When the
由永磁體122產生的吸引力128具有可變量值(即,永磁體122施加到閥構件74的頭部78上的吸引力128的強度和/或方向可變)。在操作中,螺線管22的線圈28接收電流脈衝。由永磁體122產生的吸引力128的可變量值回應於經過螺線管22的線圈28的電流的脈衝和極性而改變。一旦永磁體122的吸引力128因經線圈28的電流脈衝而增大(即得到增強),由永磁體122產生的吸引力128的增大的量值將使閥構件74移動並將頭部78定位在最接近極靴130的位置,從而充分地減小間隙136,使得當電流脈衝停止並且吸引力128減小時,存在來自永磁體122的足夠的殘餘吸引力128,以將閥構件74保持在第二位置。藉由向線圈28施加逆向的電流脈衝,永磁體122的這種殘餘吸引力128可以進一步減小。形成永磁體122的材料的矯頑性必須使得該材料的磁場對經螺線管22的線圈28發送的電流脈衝作出回應。雖然若干材料可以用於永磁體122,但在一個非限制性示例中,永磁體122由釹(Nd)製成。如圖4和圖5所示,所示示例中的永磁體122在內端124處具有南極144,在外端126處具有北極146。可替代地,永磁體122的南極144可以位於外端126,而北極146可以位於內端124,但是這種修改將需要對繞組42繞線筒26進行纏繞所沿的方向和/或電流脈衝的控制方法進行相關的改變。使其不同於下面提供的控制方法。
The
當永磁體122的吸引力128的可變量值大於偏
置部件118的偏置力120時,吸引力128使閥構件74朝向第二位置(圖5)移位。另一方面,當吸引力128的可變量值小於偏置部件118的偏置力120時,偏置部件118的偏置力120使閥構件74朝向第一位置(圖4)移位。換言之,當永磁體122產生的吸引力128強到足以克服偏置部件118的偏置力120時,永磁體122將閥構件74拉(即吸引)向自己,使其從第一位置移到第二位置。當永磁體122產生的吸引力128弱於偏置部件118的偏置力120時,偏置部件118使閥構件74返回到第一位置。吸引力128的可變量值大於或小於偏置力120取決於經螺線管22的線圈28的電流脈衝的極性。

參照圖3,閉鎖控制閥組件20可以進一步包括控制電路148,控制電路148藉由第一電引線150和第二電引線152電氣地連接到上述至少兩個電連接器52。第一電引線150和第二電引線152將電流從控制電路148傳送到上述兩個電連接器52,並且可以採取多種形式,包括但不限於印刷電路板(PCB)上的金屬絲線或導電跡線。第一電引線150電氣地連接到第一端子54,第二電引線152電氣地連接到第二端子56。在運行中,控制電路148經由第一電引線150和/或第二電引線152向線圈28供應一個或多個電流脈衝。下面的表I給出了示例性操作控制方法:
表I中的標為“紅線”的列列出了供應到第一電引線150的電流的電壓。表I中的標為“黑線”的列列出了供應到第二電引線152的電流的電壓。表I中的標為“流路打開”的列列出了這樣的端口,在閥體孔64內的這些端口之間存在(即打開)流體流動路徑,其中“1”表示第一端口96,“2”表示第二端口98,“3”表示第三端口100,“2-3”表示第一流體流動路徑102,“1-2”表示第二流體流動路徑104。表I中的標為“流動路徑關閉”的列列出了這樣的端口,在閥體孔64內的這些端口之間不存在(即關閉)流體流動路徑,其中“1”表示第一端口96,“2”表示第二端口98,“3”表示第三端口100,“2-3”表示第一流體流動路徑102,“1-2”表示第二流體流動路徑104。
The column labeled "red line" in Table I lists the voltage of the current supplied to the first
表I中的頂行(即第一行)對應於使閥構件74來到第二位置並保持在第二位置的操作狀態(圖5)。在此操作狀態下,永磁體122的吸引力128的可變量值回應於控制電路148向第一電引線150供應正電壓電流脈衝、並向第二電引線152供應零伏的電壓而增大。永磁體122的吸引力128的可變量值的這種增大使永磁體122將閥構件74從第一位置拉到第二位置,並抵抗偏置部件118的偏置力120而將閥構件74保持在第二位置。在第二位置,閥座接合構件82打開第一端口96和第二端口98之間的第二流體流動路徑104,並且關閉第二端口98和第三端口100之間的第一流體流動路徑102。如表I所示,供應到第一電引線150的電流的
正電壓脈衝可以為例如+12伏的直流電(VDC)。
The top row (ie, the first row) in Table I corresponds to the operating state in which the
表I中的底行(即第二行)對應於閥構件74返回到第一位置的操作狀態(圖4)。在此操作狀態下,永磁體122的吸引力128的可變量值回應於控制電路148向第一電引線150供應零伏的電壓、並向第二電引線152供應正電壓脈衝電流而減小。永磁體122的吸引力128的可變量值的這種減小導致閥構件74隨永磁體122的吸引力128的可變量值下降到低於偏置部件118的偏置力120的量值(即,變得比偏置部件118的偏置力120弱)而返回到第一位置。在第一位置,閥座接合構件82打開第二端口98和第三端口100之間的第一流體流動路徑102,並關閉第一端口96和第二端口98之間的第二流體流動路徑104。如表I所示,供應到第二電引線152的正電壓電流脈衝可以為例如+12伏的直流電(VDC)。應當理解,當線圈28為供應有電流時,永磁體122的吸引力128的可變量值保持恆定。
